Re: MI-L reading the map header file

[Jaromir Svasta]

I am long trying to find a better way to get types of all objects stored  
in a map other than looping through all objects in a table. I know it must  
be somewhere, because MapInfo knows it immediately - for instance, after  
pressing the style override button, only those style buttons are offered  
that correspond to bject types found in a table (region, line, point or  
text). Is it in a map header? Is the map header documented somewhere?
Thanks!
(I hope my english is comprehensible...)

hi,
sometime ago i asked if it was possible to determine the number of  
features
within a tab file by directly reading the .data or .map file.  somebody
kindly supplied the following code

Open File strMapFile for binary as #1 ByteOrder LowHigh
Get #1, 317, nPoints    ' nPoints etc are integer variables
Get #1, 321, nLines     ' plines + lines + arcs
Get #1, 325, nRegions   ' regions + rects + ellipses
Get #1, 329, nText
however, this only seems to work within MapBasic.  I am trying to do the
same thing in VBA but to no avail.  Does anybody have any idea what the
problem could be?
Thanks
Daniel
